CARD-SETTlNG-MACHINE REST.

SPECIFICATION forming part of Letters Patent No. 404,036, dated May 28, 1889.

Application filed March 26, 1889. Serial No. 304,645. (No model.)

To all whom it may concern-.-

Be it known that I, NATHAN O. Es'rEs, a citizen of the United States, residing at Smithfield, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improved Card-Setting-Machine Rest; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to card-setting machines used in the manufacture of cardclothing, and more particularly to the rest used in card-setting machines which supports the wires as the second bend is being made in the wires. I

The object of my invention is to improve upon the present construction-of the rest in a card-setting machine and to make the part on which the wires rest movable and adjustable; and my invention consists in certain novel features of construction of the rest and 2 5 its connecting parts, as will be hereinafter fully described, and the nature thereof indicated by the claims.

In card-setting machines of the class to which my invention relates the wire after re- 0 ceiving its first bend is thrust through the clothing, and the two ends project out from the clothing and extend over and bear on a rest, which furnishes a firm edge to support the wires while the second bend is being made 3 5 in the wires. The rest on which the wires are supported when the second bend is being made has heretofore been made stationary laterally, and the card-clothing is moved back and forth in front of said rest as the 0 wires are inserted. The two ends of the wire,

after being thrust through the clothing, always extend over the same points in the upper edge of the rest as the second bend is being made in the wires, all in the well- 5 known manner familiar to those using cardsetting machines.

It has been found in practice, and especially where steel wire is used in a card-setting machine, that by reason of the wires always extending over the same points in the'upper edge of the rest as the second bend is being made in the wires a slight depression or groove will be made in the top edge of the rest at the points where the wires bear, which will increase by the continued use of the machine, and it is necessary to constantly remove the rest to grind down the bearing-edge thereof and remove the depressions or grooves therein made by the wires, in order to make the edge of the rest true and even, so that the bends in the wires willbe made uniform and the card-clothing be properly made.

My present invention is designed to Overcome the necessity of constantly removing the stationary rest for the purpose of grinding out the depressions or grooves made in the bearing-edge thereof by the wires, and I carry out my invention by combining with the stationary rest and its supporting stand or frame of ordinary construction a thin blade or sheet of hardened steel, which is movable laterally and adjustable, and the upper edge of which serves as the rest on which the wires are supported and bear when the second bend is being made in the wires. 7 5

WVhen by the constant wear of the wires depressions or grooves are made in the wearing edge of the supplemental rest, said rest is moved back or forth laterally or endwise on the stationary rest, so as to present an even and true edge, and also new points of wear for the wires. 7

WVhen the supplemental rest has a number of depressions or grooves in its wearing edge, it is removed and replaced by a new one, the expense of the same being small.

Referring to the drawings, Figure l repre sents a plan View of a rest and its supporting-stand used in card-setting machines detached and with my improvements applied 0 thereto. Fig. 2 is a vertical section on line :0 Q6, Fig. 1, looking in the direction of the an row, same figure; and Fig. 3 represents the movable supplemental rest-blade detached.

In the accompanying drawings, 1 is the 5 stand or frame, of the ordinary construction used in card-setting machines of the class to which my improvements relate, and adapted to be secured in its proper position in said machine. The upper end of the stand or frame 1 is made U-shaped, (see Fig. 1,) and upon the forward ends of the U-shaped part of said stand is supported and secured the stationary rest 2, of the ordinary construction, having the vertical rest-blade 2' or rest proper, and the rearward-projecting arms 2, extending at right angles from the ends of said restblade 2. The arms 2 have slots 3 therein to permit of moving the rest 2 back and forth on its supporting-frame, and said arms are secured to the stand or frame 1 by screws 4, all of the ordinary and usual construction and operation in the class of card-setting machines to which my invention relates.

It will be understood by those skilled in the art that the wires as the second bend is being made in them extend over and are supported upon the upper edge of the rest-blade 2, as indicated by dotted lines 5, Figs. 1 and 2, and it will be observed that by means of the slots 3 in the arms 2" of the rest 2 and the screws 4 the rest may be moved forward and back on the supporting-stand 1 and adjusted toward or away from the wires and the cloth in which they are secured to make the bend in the wires shorter or longer, as desired. It will also be observed that there is no lateral motion to the rest 2 on its supporting-stand, and that the wires 5 will always extend over the same points in the upper;

edge of the rest-blade 2.

As heretofore stated, by reason of the wires extending over the same points in the upper edge of the rest blade 2, depressions or grooves are soon worn in said blade, and it is i necessary to constantly remove the entire rest 2 and to grind out said depressions or grooves or substitute a new rest.

In my invention I combine with the rest 2 and the stationary rest-blade 2 a supple mental movable rest-blade, 6, which is adj ustj able laterally or endwise.

rest-blade 2'.

The supplemental rest-blade 6 is made suf-I ficiently wide so that the upper edge will eX- tend above the upper edge of the rest-blade 2, and the Wires will rest and be supported upon the upper edge of the supplemental restblade 6 and not upon the. upper edge of the rest-blade 2'.

The supplemental rest-blade 6 is secured in fplace and held firmly against the rest-blade 2 in this instance by means of the twowedgepieces 7 and the holding-screws 8. The rearj lower edge of each wedge-piece 7 is made bevi eled, and is adapted to bear against a shoulder, 9, made in the upper surface of the arms 1 2 of the rest 2, and the front edge of each wedge-piece 7 is made slightly beveled and is adapted to bear against the inner surface of the supplemental rest-blade 6. (See Fig. 2.)

By screwing in the screws 8 the front edge of wires. made in the upper edge of the supplemental the wedge-pieces 7 is drawn down and made to bear against the inner surface of the supplemental blade 6 and hold the same firmly against the rest-blade 2', and by screwing out the screws 8 the front edge of the wedgepieces 7 is released, allowing the supplemental rest-blade 6 to be moved laterally or endwise, or to be removed entirely.

I have shown in the drawings and described above one way of securing the supplemental rest-blade 6 to the rest-blade 2' but it will be understood that any other equivalent or wellknown way of securing the same may be employed, as by means of a clamp-screw, a camwedge, &c.

If preferred, the details of construction of the rest proper and the supplemental rest: blade and the manner of combining the same together may be varied somewhat from what is shown and described. For instance, instead of a blade or thin sheet of metal to serve as a supplemental rest, I may employ acircular piece or disk supported on the rest proper or on the frame and adapted to revolve to present new points of wear for the wires as the second bend is being made in the same.

The operation of the movable supplemental rest-blade 6 will be readily understood by those skilled in the art. 7

The wires are supported by and restirpon the top edge of the supplemental rest-blade 6 as the second bend is being made in the When depressions or grooves are rest-blade 6 by reason of the wires always extending over the same points in said edge, as above described, the holding-screws 8 are loosened and the wedge-pieces '7 released, so that the supplemental rest-blade 6 may be moved backer forth laterally or endwi'se to present new points on its upper edge for the wires to rest upon. The screws 8 are then tightened and the supplemental rest-blade 6 clamped in its new position.

IIO

When the upper edge of the supplemental rest-blade '6 is full of depressions or grooves, the blade may be reversed and the lower edge 3 made the upper edge; or a new blade may be substituted. I

The advantages of my invention will be readily appreciated by those skilled in the art. The supplemental movable rest-blade may be applied to the stationary rest of ordinary construction now in 'genera-l use in the class of card-setting machines to which my invention relates without changing the construction of said stationary rest or the stand or frame upon which it is supported.

By the use of the supplemental movable rest-blade a large number of new points of wear for the wires may be obtained, thus avoiding the necessity of grinding out or removing the depressions or grooves made in the blade, making it 'much less expensive and much less labor for the operator, and procuring a greater uniformity in the work.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a card-setting machine, the combination, With the rest and its supporting-frame, of a supplemental adjustable rest adapted to present new points of Wear for the Wires which are supported thereon when the second bend is being made, substantially as set forth.

2. In a card-setting machine, the combination, with the rest adjustable back and forth on its supporting-frame, of a supplemental rest blade adjustable laterally or endwise and means for securing the same to the rest, substantially as and for the purpose stated.

3. In a card-setting machine, the combina- 15 tion, with the rest adjustable back and forth on its supporting-frame and means for securing it in place, of a supplemental rest-blade movable laterally or endwise on said rest and Wedge-pieces and holding-screws for securing 20 said supplemental rest in place, substantially as shown and described.
